CARBURETER.

Specification of Letters Patent.

Patented June ii, rare.

Application filed September 28, 1916. Serial N0. 122,667.

To all whom it may concern:

Be it known that I, JOHN THOMAS GRA- HAM, engineer, subject of the King of Great Britain, residing at 13 Chapel street, Halstead, Essex, England, have invented new and useful Improvements in or Relating to Carbureters, of which the following is a specification. g

This invention relates to carbureters for use in vaporizing hydrocarbons for illuminating, cooking, heating and like purposes and of the type comprising a casing in which are positioned two series of oppositely inclined plates either plain or perforated, disposed one above the other, down which measured quantities of hydrocarbon are allowed to flow.

The object of this invention is to provide an improved construction of carbureter.

To this end, each inclined plateis provided with a lip or the like for the purpose of collecting the spirit and depositing the excess on to the next inclined plate and so on. Each lippreferably consists of curved metallic gauze.

The means provided for supplying measured quantities of the hydrocarbon to the inclined plates consist of a cup pivoted to a lever disposed in the reservoir and adapted. to pickup quantities of the hydrocarbon from a well or recess in the bottom of the reservoir and discharge same into a regulator fitted to the supply pipe of the carbureter.

I am aware that it has been proposed to supply hydrocarbon to carburetors by means of a cup or dipper pivoted in the tankto a resilient arm operated by means of a rod and cranks said cup depositing thehydrocarbon into a funnel fitted to the supply pipe of the carburetor.

The invention will now be described with reference to the accompanying drawin s in which Figure 1 isja front view, part y in section, of a carburetor made in accordance with this invention; Fig. 2 is a back view, partly in section, of the carbureter Figs. 3' and 4 are, respectively, a plan view and an edge view of one form of inclined plate;

Figs. 5, 6 and 7 show modified forms of plates; and 7 Figs. 8 and 9 are enlarged, vertical, sectional views of the dispensing vessel comprised in the regulator.

a is the carbureting chamber or casing in the inside of which are fitted two series of oppositely inclined metal plates 1), b, alternately disposed one above the other; for

example, half of the plates are inclined downward toward the left and the other half toward the right. Each inclined plate is provided with a lip c. p

The lips preferably consist of curved metallic gauze or other. suitable reticulate material. Thebottom of the casing a is provided withan air inlet pipe (2 and the top of the casing'is provided with a petrol or the like supply pipe e and also an outlet pipe f to the usual gas holder y for the conveyance of the mixture.

The inclined plates 12, b, may be formed with tongues b, which are slightly depressed, as shown in Figs. 3 and 4, or with perforations 6 (Fig. 5), the perforations and the slits which produce the tongues being too small to allow drops to form. If preferred, moreover, the plates may be provided with gauze-covered slots 6 (Fig. 6), or they may take the form of skeleton frames g: hazing gauze b stretched thereover, as in The said supply pipe e is so arranged that the spirit discharged therefrom is caused to drop onto the uppermost inclined plate I) and form a thin film thereon and percolate through and form a film on the underside also and then be absorbed by the reticulated lips. Petrol not vaporized'on the top plate collects on the lips and drops to the next inclined plate and so on.

While the spirit is percolating down, a supply of air is forced up into the casing from the pump to and is caused to follow a circuitous path between the plates 6 and come in contact with the petrol on both sides of the plates.

The petrol is "aporized and the air becomes carbureted in determined proportions of air and vapor and passes on through the outlet pipe 7. a

m is the reservoir, in the inside of which is positioned a regulator 00 comprising a tlb funnel shaped vessel 9 (Figs; 8 and 9) conby a valve h. Said funnel-shaped vessel is near the funnel g in order that the cup may be tilted when in position over the funnel The position of the regulator tap determines the amount of petrol passing to the carbureter or through the overflow pipe 8 back into the reservoir m. By this means the exact proportion of petrol and air is correctly obtained.

The valve h is provided with an indent and pointer u for indicating the position thereof.

ll claim as my invention 1-- 1. ln a carburetor, the combination of a vertical chamber having both a petrol supply means and an outlet for the carbureted air at its top; two series of oppositely-im '30 clined plates alternately disposed one above another in said chamber below said supply means; each plate being provided with relatively-fine apertures and having a curved, metal gauze lip at its lower edge, so that the petrol, as it passes from plate to. plate, will form a thin film on the upper side of. the plate, then percolate through the apertures in the plate and form a thin film on the naeaaea under side of the plate, while the surplus into contact with the films of petrol on both sides of the plates.-

2. in a earbureter, the combination of a vertical chamber having both a petroh supply means and an outlet for the carbureted air at its top; two series of oppositely-inclined plates alternately disposed one aboveanother in said chamber; each plate being provided with groups of line perforations and having'a drainage device at its lower:

edge for the surplus petrol, so that the petrol,

as it passes from plate toplate, will form a thin film on the upper side of the plate, then pereolate through the perforations in the plate and form a thin film on the under side of the plate, while the surplus petrol will collect in the drainage device on the plate and be discharged therefrom upon the neat lower plate; and means for supplying air to said chamber below the lowermost plate, whereby the air is caused to follow a circuitous path through the chamber between said plates and come into contact with the films of petrol on both sides of the plates.

In testimony whereof l have signed my name to this specification in the presence of two subscribing witnesses.
